PHP is a widely-used general-purpose scripting language that is
especially suited for Web development and can be embedded into HTML.

The sscanf() PHP function contains an array boundary error that can be
exploited to dereference a null pointer. This can possibly allow the
bypass of the safe mode protection by executing arbitrary code.

A remote attacker might be able to exploit this vulnerability in PHP
applications making use of the sscanf() function, potentially resulting
in the execution of arbitrary code or the execution of scripted
contents in the context of the affected site.
